## Diagonal 1 of Quadrilateral Solution

STEP 0: Pre-Calculation Summary
Formula Used
Diagonal 1 of Quadrilateral = sqrt(Side A of Quadrilateral^2+Side B of Quadrilateral^2-(2*Side A of Quadrilateral*Side B of Quadrilateral*cos(Angle B of Quadrilateral)))
d1 = sqrt(Sa^2+Sb^2-(2*Sa*Sb*cos(∠B)))
This formula uses 2 Functions, 4 Variables
Functions Used
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Diagonal 1 of Quadrilateral - (Measured in Meter) - A Diagonal 1 of Quadrilateral is a straight line joining two opposite corners of the Quadrilateral.
Side A of Quadrilateral - (Measured in Meter) - Side A of Quadrilateral is the measure of the length of the Side A of the Quadrilateral.
Side B of Quadrilateral - (Measured in Meter) - Side B of Quadrilateral is the measure of the length of the side B of the Quadrilateral.
Angle B of Quadrilateral - (Measured in Radian) - Angle B of Quadrilateral is the space between two intersecting lines (side a and side b) or surfaces at or close to the point where they meet.
STEP 1: Convert Input(s) to Base Unit
Side A of Quadrilateral: 10 Meter --> 10 Meter No Conversion Required
Side B of Quadrilateral: 9 Meter --> 9 Meter No Conversion Required
Angle B of Quadrilateral: 70 Degree --> 1.2217304763958 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
d1 = sqrt(Sa^2+Sb^2-(2*Sa*Sb*cos(∠B))) --> sqrt(10^2+9^2-(2*10*9*cos(1.2217304763958)))
Evaluating ... ...
d1 = 10.9286949907727
STEP 3: Convert Result to Output's Unit
10.9286949907727 Meter --> No Conversion Required
10.9286949907727 10.92869 Meter <-- Diagonal 1 of Quadrilateral
